28mm Long Neck PET Preform Manufacturer & Supplier PCO 1810

A 28mm long neck PET preform refers to a plastic preform with a 28mm diameter neck finish and an extended neck length -- typically used for carbonated soft drinks (CSD), water, juice, and other beverage applications. The "long neck" design provides a deeper thread engagement area, ensuring a secure, leak-proof seal with compatible closure caps. It is one of the most widely used preform neck standards globally due to its versatility and compatibility with high-speed blow molding and filling lines.

Yes. Our 28mm long neck PET preforms are fully compatible with PCO 1881 closures -- the globally dominant lightweight cap standard adopted by major beverage brands including Coca-Cola and PepsiCo. The PCO 1881 finish reduces cap weight by approximately 30% versus the older PCO 1810 standard, contributing to lower material costs and a smaller environmental footprint. We precision-manufacture every neck finish to ±0.1mm tolerance to guarantee consistent cap torque performance on your filling line.

We offer flexible MOQ options designed to accommodate businesses at every scale -- from emerging beverage startups to large-volume global brands. Standard stock preforms are available from smaller trial quantities, while custom color or custom mold orders typically require higher volumes to offset tooling investment. Contact our team with your specific requirements and we will provide a tailored MOQ and pricing structure that aligns with your production schedule and budget.

Absolutely. We strongly encourage prospective buyers to request physical samples before committing to a bulk order. Sample preforms allow your QC team to verify dimensional accuracy, wall thickness consistency, clarity, and blow molding performance on your existing equipment. Standard samples from existing molds can typically be dispatched within a few business days. Custom-spec samples may require additional lead time depending on tooling requirements. Sample shipping costs are generally borne by the buyer.

Lead time depends on order volume, customization requirements, and current production scheduling. For standard stock 28mm long neck preforms, lead time is typically 15-25 business days after order confirmation and deposit receipt. Custom color or new mold orders may require an additional 20-30 days for tooling and first-article approval. We operate 60+ injection molding machines to maintain high throughput and minimize delays. Our team proactively communicates production milestones to ensure your supply chain stays on schedule.
